The bandage impregnating apparatus comprises a vessel l0 for the impregnating liquid, and if desired a temperature control means, such for instance as a lower Velongated vessel Il of heat-Y resistant glass adapted to receive a heat exchange ing liquid of the desired temperature. As shown, a rectangular frame |72 is disposed over said vessel providing a large intra-marginal opening I3, (left of Fig. 2) about as large as and over the vessel l I. A molding l5 secured o n the lower face of the frame around said opening' is pro,- vided with an inner groove It received on the upper edge of the vessel, the molding being cut away as at I1 (Fig. 3) to accommodate the handle I8 of the vessel.

The upper container lo. is similar to and spaced from, the lower container and nested in said opening I3 andthe lower container and said heat exchanging liquid and adapted to contain the impregnating liquid adapted toA be warmed or cooled by heatpassing through the lupper' conf tainer from orto said liquid of the lower vessel.

A pair of bearing ears 20 projecting outwardly and upwardly from one end member of said frame l2 have upwardly open bearing slots removably receiving a headed supply spindle 2l (Fig. 1). adapted to carry a supply roll 22 of strip bandage material to be impregnated. A pair of guide brackets 2 3 adjustably secured on said end mem-f. ber of the frame are provided with vertical guide pieces 24 adapted to engage ends of the roll.k

A pair of bearing blocks 21', 28 are mounted on the side members of the frame near the otherI end 29 oi the frame, the block 2l being provided with a bearing bore 3U opening toward the other block. The block 28 has upstanding lugs 3|, 32 (Fig. 2) providing an intermediate U-shaped poreI tion providing an upwardly open bearing recess 33 the lower part of which is alined with said bore 30,. A taire-up or Winding shaft 3.5 rotat able in said bore kand recess is provided in the part adjacent to the recess `33 with a transverse View of the ap- 2V f i inner end part of the countersink 39 and engaged l by a helical spring. 43 compressed between said head anda threaded plug 44 in the outer end of the countersink for yieldably holding the pin in said groove, whereby the shaft is yieldably held against outward and upward movement, and may" be easily removed from the bearing blocks. i v

A crank handle 45 has a hub 46 removably frictionally held on the slotted end of the shaft and carrying a transverse pin 41 engaged in said end slot 36, whereby revolution rof the crank handle constrains the shaft to rotate. Said shaft has a long longitudinal slot 48 intermediately therein adapted Vto receive the -end of a bandage to V.facilitate winding the bandage from said spindle-2l onto the shaft. Y

Anapproximately U-shaped 'depressing guide member 50 (Figs. 2 and 4) near the supply roll ZIcOmpriSeS-upright arms 5l within the vessel having hooked ends 52 disposed over the edge of theyessel and removably engaged inthe adjacent bores/53 infthe frame. `Saidguide member. 56. also comprises a straight horizontal transverse lower yoke 55 near the bottom 56 and sides of the upper vessel and is adapted to engage over an intermediate part 22a of the bandage materialA passing from the supply to the take-up shaft, Vto hold it deep in the impregnating liquid.

A handle for said guide member comprises a thin Y horizontal bar-51 having upperand lower rounded edges andprovided-with vertical end grooves 58 (Fig. l) in which the upper intermediate part of the arms 5l :justY below the hooked end are secured. lA .i 2,' x A transverse lifting or supporting guide near theitake-up `shaft comprises a wire r6l), 6|, 62 (Figs. 1 and 5) bent to forma middle horizontal supporting. and guiding part 66 of'a length substantially equal to the width -of thefbandage, upright guide Varms 6I at the ends of the supporting part extending above the-'level of the top edge of the vessel, the end Yparts 62 of said wire being bent outwardly and slightly `toward -the take-up shaft and then .turned vdownwardly and removably received inthe adjacent bores in the sider members of the frame. Said supporting part 6B raises the bandage as itpasses tol the take-up'roll 647 scraping off excess liquid and holding the bandagein position to be out across with scissors between said partvv60 and theshaft whenV enough has been received onY `the take-up roll whereupon the take-up shaft may beremoved against the yielding action of said pin 40, afterwhich another similar shaft may be placed in the bearings, the detachable crank handle 45 appliedV thereto, the out end ofthe bandage threaded into the slot 43, adapting the apparatus for further operation. 'Ihe detached take-up shaft with the' roll 64 of bandage material thereon,fmay then serve as a convenient handle to hold -the impregnated bandage roll while the bandage is. being wound around the limb or part to which it is applied. Y 1- .When the bandage'material of the roll `22 is exhausted, the spindle 2l may beremoved and a threaded into the slot 48, after'which a turn or two of the crank will wrap the strip about the shaft Vand thus secure the same to the shaft. The guide means 50 is then replaced to the position of Fig. 2, causing the traveling strip to be immersed in the impregnating liquid.

During the'operation of treating the bandage with the impregnating fluid and during the winding operation, the treated bandage 22, is passed `over the lifting and supporting guide 60, 6l and 62, as disclosed in Figs. 1 and 5, and the bandage guide portion 60, Fig. 5, tends to act as a doctor or scraper, as well as a guide, to remove excess The re. moved excess fluid falls back into the vessel l0.

impregnating fluid from the bandage.

In some forms of treating bandage material,

vthe medicinal iiuid may have to be heated to re'- new roll slipped in its place. The depressing guide means 56 is then removed and the bandage duceits viscosity, and to hasten its absorption Y into the bandage and under this condition, sufficient water may be placed in the lower vessel ll, and the device'placed upon a heating means, so that the impregnating uid may be controllably heated to desired temperatures, during the bandage impregnating operation.

From the foregoing, it `will be noted that the treated bandage may be treated, wound intoa rol-1.22,l and applied to the patient, without the o necessity of touching the bandage'itself by the hands, thus preservingl the bandage fr om unsanitary contacts. 'I
